Abstract

The invention provides a ruminant type kitchen waste treatment device and method. The ruminant food waste treatment device includes a circulation system, a screw press mechanism, a convergent solid removal mechanism, a slurry separation mechanism, an oil-water precipitation mechanism, and a digestion mechanism. In the ruminant food waste treatment method, during the food waste feeding period, the ruminant food waste treatment device processes the food waste that is put in real time; The kitchen waste is processed in reverse circulation, or the inside of the pressing mechanism is cleaned with external liquid. In view of the fact that the generation time of kitchen waste is concentrated in the time of three meals, resulting in contradictions in processing time and amount of kitchen waste, and other kitchen waste treatment problems arising therefrom, the invention comprehensively utilizes the time inside and outside of three meals to carry out operations , Realize the reduction of the solid phase of kitchen waste, the separation of oil and water in the liquid phase and rapid digestion, effectively solve the problem of kitchen waste disposal.

Description

technical field

[0001] The present invention relates to the technical field of kitchen waste treatment, in particular to a ruminant-type kitchen waste treatment device and method. Background technique

[0002] The extremely high moisture content and high oil content of kitchen waste have a great impact on the subsequent recovery and treatment effect of kitchen waste treatment. It is very easy to cause the kitchen permeate to directly penetrate into the groundwater layer, resulting in secondary pollution and the phenomenon that most of the kitchen organic matter is wasted. At present, the pretreatment technology of kitchen waste can effectively reduce the moisture content and oil content of the food waste, and provide good solid-phase materials that meet the oil content and moisture content for the subsequent treatment of the food waste. Materials that are difficult to dehydrate (High viscosity, high dispersibility) processing and high requirements for the speed and efficien...
